To all whom t may concern: v

Be it knownthat I, JOHN J. I-IAssnLBAoH, a citizen of the United States,residing at Detroit, in 'the county of l/Vayne and State of Michigan,have invented certain new and useful Improvements in Racks, of which thefollowing is a specification.

This invention relates to improvements in racks and particularly to rackfor filing blue-prints, maps, drawings and similar flat sheets.

The objects of this invention are: y

First, to provide an improved rack for filing blue-prints or drawingswhich will permit the filing of a large number of drawings` in a smallspace and which can be swung back'against the wall when not in use.

Second, to provide a rack for filing drawings which oan be constructedat a low cost and which will economize the space needed for filingprints and drawings.

Third, to provide an improved rack for filingdrawings having a pluralityof independently removable carriers so constructed that allrelated'drawings or prints can be carried by a single carrierV andremoved from the rack in a group for examination without removing theother carriers or drawings. Y

Fourth, to provide an improved rack for :tiling drawings having aplurality of removable carriers, each carrier being so connumber ofprints with one of the upper corners free to permit examination of therewithout removing the prints from the carrier.

Fifth, to provide removable carriers having novel clamping means, bywhich the sheets can be bound or secured in the carriers, said clampingmeans being quickly releasable.

Further objects, and objects relating to economies of operation anddetails of construction, will detinitely appear from the detaileddescription to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. My invention is clearlydefined and pointed out inthe appended claims.

A structure constituting a preferred emthe data usually placedbodimentof my invention is illustrated in the accompanying drawings, forming apart of this specification, in which Figure I is a view in sideelevation of a raclcconstructed in accordance with my invention.

In the drawings, similar reference numerals indicate similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Considering' the numbered parts of the drawing, my invention comprises arack which is adapted to be supported on the wall and to carry aplurality of independently removable carriers in which the prints,drawings or sheets to be filed are clamped. The brackets 20 are fastenedto the wall 2l by the screws 22. The bar 25, which is here shown as ofsquare, tubular construction, has a head 23 disposed between thebrackets 20 Patented Mar. 26, 1913.;

and carrying the pins 211 which are journaled in the brackets 2G. Thesepins ing thus journaled permit the bar 25 to swing in a horizontf-ilplane. lfhe hollow bar 26 which is of slightly greater cross sectionthan the bar is slidably upon said bar rlhis bar 26 carries the endplates A28 which are preferably of sheet metal stamped to the properform. These end plates are tapered so that therlower end thereof isnarrower thanthe top and are provided with a plurality of downwardlynclined slots at the sides thereof, the inner end of each slot beingoffset inwardly with reference to the slot :.bove. '.lhe ears 30 areprovided on the upper corners of the end plate and are that they may beused to hold a card carry ing data referring to the drawings filed in.the rack. The ear 31 is stamped out from the body of the end plate toserve as a finger grip in moving the rack on the bar 25.

"hisraclr is designed to carry a plurality of independently rfeinovablecarriers in which the sheets to be tiled can be clamped or bound. Therack shown in the drawings will carry six of t frese carriers and itscapacity can be increased by providing end plates having additionalslots. 1Sach carrier comprises a bar 32, approximately as long as therack., having the portions 33 turned downwardly at the corners thereofto serve as legs for supporting the carrier when taken out of the rackand laid on a table in order to examine the drawings therein. i portion34 at each end of the bar 32 is twisted so as to lie in a plane at anangle to the plane of the bar 32 and serve as pins for supporting thecarrier in the rack. rlhe angle at which these pins Si are twisted issuch that, when they are inserted in the slots 29, the carrier will liein a vertical plane. rllhe portions Bil being flat they prevent turningor twisting of the carrier when in place in the rack. rt one end of thebar 32 there is provided the block 35 having an undercut, inclined facei556. A clamping plate 37, which is slightly narrower than the bar 32,has one end thereof inserted beneath the inclined face 36 of the bleek3o and when said clamping plate is forcee agai @t the bar 32 by suitableclamping or locking means the sheets are securely bound in -theIcarrier. rlfhe plate 37 is shorter than bar 3&3 for a purpose which willbe forth here inafter.

In Figs. V11 to X1 inclusive, 1 have shown one form of clamping means.1n this form, straps 38 are secured to the bottom face of the bar 32 andcarry bearing blocks 89 in which one arm Ll-O of a roch arm has abearing. Each of these bearing blocks has a' curved slot and the pinlcarried by the arm 440 is disposed in said slot. rlhe rock arm has aportion 43 extending at right @il bef mounted bent parallel `to theplate so angles to the arm 40 and an arm le extend l ing right angles tothe portion 43 and the arm 110. The arm 4:0 when in position in thebearing block 39 lies parallel to the bar while the arm dat extends overthe clamping plate 37. A pin 4:5 is carried by the end of each arm f1.4and a lever 16 is fulerumed on each of said pins 45, each of said leversbeing provided, at one end, with the nose L17 adapted to engage theupper surface ofthe clamping plate 37. The inner ends of the levers 11Gare connected by the link d8, the ends of which are pivotally 'connectedto the inner ends of the levers 4G by the pins 119. 'fr screw 50, havingthe head 51, threaded through the link 118 and the end of said screwengages the uppersurface of thc clamping plate 37.

1n Figs, X11 to XV inclusive, 1 have shown another form of clampingmeans which, in some cases, is to be preferred to the form abovedescribed in that it requires less space. rl`he blocks 52 are secured tothe lower surface of the bar 39j and. the shaft 53 is journaled in saidblocks. The worms are fixed on the shaft 53 and said shaft is providedwith the head 55 by means of which it may be rotated. Blocks 56 aresecured to the upper surface of the bar 32 and a stub shaft- 57 isjournaled in each of said blocks 56 and extends through the bar carryingon its lower end, beneath the bar 32, a gear 58 meshing with the worinlllliper arms 59 are fixed to the upper ends of the shafts 57 and wedges60 are provided on the upper surface of the clamping plate so that thewiping arms 59 will engage said wedges the shaft 57 is rotated so as toforce the clamping plate 37 toward the bar B2. 1 have indicated thesheets bound in the carrier by the reference character A.

From the description of the parts given above, the operation of mydevice should be very readily understood. As pointed out above, the bar25 is so mounted in the brackets 2O that it may be swung in a hori-'.fcontal plane so that the rack may be swung against the wall toeconolnize space and moved to a position at right angles to the vallwhen it is desired to remove drawings from the rack. The rack properconsists of the hollow bar 26 carrying the end plates 28 and the rackcan be moved away from the wail by sliding the hollow bar 2G on the harQ5. The end plates of the rack have the clined slots 29 which receivethe pins 3 at the ends of the carrier. s already pointed out, the pinsare fiat and lie in a plane at an angle to the plane of the earrier sothat the carrier will lic in a vertical plane when mounted in the rack.The clamping plate 37 is shorter than the bar 32 of the Carrier so thatthe upper right hand corners of the drawings or sheets bound in thecarrier are free and one may examine data on the sheets at this pointAwithout removing the sheets from the carrier. These carriers areindependently removable from the rack and drawings or prints may begrouped or classified by filing all the prints of one group or class ina single carrier. If the drawings in this group are to be eX- amined,the carrier can be removed from the rack without disturbing the othercarriers. The slots 29 are so arranged that the sheets in the carriercarried by the upper slots will lie in front of the sheets carried bythe other carriers ,so .that any carrier can be removed without removingthe others. when removed can be laid flat being supported by the legs33.

The sheets are bound in the carrier between the clamping plate 37 andthe bar 32 and means are provided for firmly forcing the clamping plateagainst the sheets to bind them against the bar. This clamping means isof such a nature that it will exert a considerable pressure on theclamping plate and will lock it positively but will, at the same time,be quickly releasable. In Figs. VII to XI inclusive, I have shown oneform of clamping and locking means, while, in Figs. XII to XV inclusive,I have shown another form of clamping and locking means which I preferto employ in some cases.

In the form shown in Figs. VII to XI, as the operator turns the screwthe end thereofwill bear against the clamping plate 37 and will forcethe link 48 away from plate 37. Said link 48 is connected to the ends oflevers 46, which are fulcrumed on the pins 45, so that the nose 47 ofeach lever bears down on the clamping plate 37. As a result, when thescrew 50 is turned, pressure is applied to the clamping plate at threeseparate points. The levers 4G are carried so that they may be swungback away from the clamping plate 37 since the pins 45 are carried bythe ends of the arms 44 of the rock arm. The movement of each of therock arms is limited by the pin 41 disposed in the curved slot 42 sothat an initial longitudinal movement of the rock4 arm is reonV a tablequired. This longitudinal movement is impossible when the screw 50 isturned down to apply pressure to the clamping plate but, when thepressure is released, the rock armscan be rotated, with the pins 4lworking in slots 42 and guiding the movement of the rock arms, so as toswing back the clamping means from above the clamping plate.

In the form shown in Figs. XII to XV inelusive, the clamping plate 37 isforced toward the bar 32, to bind the sheet in the carrier, by theengagement of the wiper arms 59 with the wedges ixed'on the uppersurface of the clamping plate. The shaft 53 carries the worms 54 and, asit is rotated,

' the stub shafts 57 are rotated through the The carrier tube slidablymounted on said bar;

vsecured to the ends of said tube,

gears. 58 lmeshing with the worms. The rotation of each stub shaftcauses the wiper arm 59 to move over the inclined surface of the wedge60 forcing the clamping plate against the sheets. By turning the shaft53 in the reverse direction, the wiper arms will be moved from over theclamping plate so that the latter can be freely removed.

I am aware that the embodiment of my invention, here shown anddescribed, can be varied considerably without departing from the spiritof my invention and, hence, I desire to claim my invention broadly asindicated by the appended claims. I have found this particularembodiment, however, to be desirable from many standpoints and,therefore, I wish to claim it specifically as well as broadly. i
